This is also called anti pumping relay. for understanding you have to understand the working of breaker. positive extends to "Low Pressure Lockout" & "Low Pressure Alarm". after maintain the pressure in breaker these NO becomes NC and when breaker closes the auxiliary of breaker get closed and simultaneously extend the positive to the antipumping relay coil by auxiliary contact. by this coil get energised and holding contact get connected and the one of the contact of antipumping coil (NC) become NO which disconnect the command supply of main breaker. by this till when the antipumping relay get energised no further command (+ve) extends to breaker closing coil. This is Antipumping/ Antihunting Relay.

What is the function of an LBB relay?
A local breaker backup relay is used to check the operation of distribution circuit breakers and to trip the feeder circuit breaker if the distribution circuit breaker fails to trip on an overload.
What do relay and circuit breakers use?
No. A relay is an electric switch and a circuit breaker is an overcurrent device.
What is function of damping relay in circuit breaker?
The anti-pumping relay is a device in circuit-breaker whose function is to prevent multiple breaker closures. For instance, if the operator gives the closing command to the breaker by pressing the close button and the breaker closes. However, a fault in the system causes the breaker to trip. Since the close command is still in the pressed condition, there is a chance of the breaker closing again and being tripped by the relay multiple times. This can damage the closing mechanism of the breaker. The anti-pumping relay prevents this by ensuring that the breaker closes only once for one close command from the control panel.
What are the disadvantage of a circuit breaker or a fuse in a circuit?
The only ones that could affect that decision to put one in is if you're planning on smoking or blowing-up that item in the circuit, or the hassle of changing a 20 cent - 5 dollar item instead of the more expensive item.

What is a switch that opens a cuircut when too much current is flowing?
Where I'm from, it's called a "circuit breaker".A circuit breaker.
What do relay and circuit breakers use?
No. A relay is an electric switch and a circuit breaker is an overcurrent device.
How is the relay effecting the bimetallic strip of circuit breaker?
The relay controls the flow of current through the circuit breaker by responding to an overcurrent situation. When the relay detects an overcurrent, it triggers the circuit breaker to open, which releases the tension on the bimetallic strip inside. This causes the bimetallic strip to bend and disconnect the circuit, effectively breaking the flow of electricity to prevent damage or hazards.
Where is the motor relay circuit breaker located on a 1989 mustang?
The motor relay circuit breaker may be found on the driver's side of the vehicle, on or near the fender apron. There is a cable that runs from it to the battery.

Why does a lawn mower keep popping the relay circut breaker?
you have a short to ground in the electrical circuit that that breaker is on.
Why does the 59n relay keep tripping the breaker?
The 59N relay may be tripping the breaker due to circuit overload, short circuit, or ground fault. Check for any faulty connections, damaged wires, or improper settings on the relay. Ensure that the relay is properly sized for the load it is protecting and troubleshoot any potential issues in the circuit.
